The biggest impact for me I think is the lack of ability to export STEP for KiCad 3D models.

I actually have to disagree. I think it really depends on who you follow. For a long time I didn't use twitter at all, but I've recently become active. The hardware hacker community (think Hackaday types) on Twitter is pretty awes

Thanks Chris! I didn't know you hang out on HN too :P You're slowly becoming a software guy after all...

Yeah! Embedded Rust on STM32* right now is pretty good! A lot of consolidation has happened in the device crates and HAL crates recently, so I'm adjusting a bit. But, it's looking good. I'm actually working on a post about re

Thanks! I did a video talking about the case a bit more: https://craigjb.com/2019/12/06/gameslab-case/ I had it fabricated for me by a company by Front Panel Express. In a DIY audiophile forum I saw peop

Yeah, Rust is great! I've used it on several production projects for work, but not for extensive embedded work before this. Embedded Rust is getting better and better! Shout out to the Real Time For the Masses project (it's an RTO

Thanks! There was definitely a lot of learning involved--I wrote up some here: https://craigjb.com/2019/12/04/gameslab-fails/ To be honest, I really don't know a good KiCad tutorial. I kind of just

The ZipCPU tutorials section is also great! They include verilog, using verilator (for simulation), and formal verification. And, personally, I think learning formal verification early is great, since it will probably be used more and more.

I've seen a split. Some people are looking for CPU acceleration. Others say Zynq effectively covers the case where FPGA designs include a soft-core anyway for high-level control, so why not make it a hard block.

Yeah, I was going to mention the PS3 too. It was the most unique hardware of the generation and definitely took the longest for devs to adjust to and learn to leverage fully.

Thanks! I actually didn't originally intend it to be for retro game emulation, more for experimenting with custom hardware for each game and with 3D acceleration hardware. But, the idea of putting retro emulators in the FPGA fabric is

I don't think 5W is too far off from what this thing draws under load. I have a 10,000mAh ~4.2V battery in it, and I get about 10 hours of life. The battery is clunky, 9.6mm thick, since it was originally intended for external phone ba

Thanks! I always recommend getting hands-on for learning more about FPGAs. FPGA boards are cheaper than ever, and you have all different ones now. I'd say get a Lattice ECP5 based board (like this year's Hackaday Supercon badge).

I didn’t phrase that well. I meant that the wafer wafer and panel level embedded technologies embedded the silicon die inside of cheaper epoxy, instead of building expensive silicon interconnect to integrate them on. They basically make a p

Package on Package has many downsides though: - The interconnect pitch is huge, 0.3mm-0.4mm. HBM memories have 1000s of I/Os - The inductance of the solder balls and the impedance discontinuities in the path mean the logic below still

I think the embedded wafer level or "panel" level packaging technologies are the mid-ground. These technologies don't use expensive silicon, and instead surround the die with cheaper epoxy. Then the interconnects are built on

It's been fun to see Dr. Subu present this concept and prototypes at several conferences, and the level of integration possible is absolutely insane. I think the industry is definitely moving toward chiplets, such as the latest AMD rel
